In the 1980s BBC docudrama 'The March',
hundred of thousands of Africans marched northwards toward the Mediterranean
to escape starvation, prompting widespread panic in Europe about an impending
'flood' of 'illegal migrants'. The current global food crisis is very
unlikely to result in mass migration, and population movements that do
occur will almost certainly take place within countries and not across
borders, and for a short-period of time only.
